Perplexity

Cascade runs deep competitive analysis

`list_similar_companies` acts as the entry point when you ask Windsurf to map out a market sector. Cascade takes the output list, automatically triggers `get_company_details` for each entity, and extracts their core metrics. You don't have to prompt the agent for each step of this research. This MCP toolset handles the loop itself, compiling a complete spreadsheet of competitors in your workspace.

Map funding histories using this MCP Server

`search_funding_rounds` lets Cascade find recent investment activity in any tech vertical. After locating target rounds, the agent pulls granular transaction data with `get_funding_round_details` to verify deal sizes. This autonomous loop bypasses manual database searching entirely. Your workspace gets updated with clean, structured funding tables without you writing a single line of integration code.

Track talent movement and team growth

`get_company_employees` extracts historical headcount metrics directly into your Windsurf editor. Cascade uses this raw data to calculate growth velocity and spot hiring surges before they hit the news. By pairing these workforce details with `get_company_news`, the agent builds a timeline of company momentum. You get an objective view of execution speed without reading biased PR announcements.
